Trait conch_runtime::error::IsFatalError

pub trait IsFatalError: Error {
    fn is_fatal(&self) -> bool;
}

Determines whether an error should be treated as "fatal".

Typically, "fatal" errors will abort any currently running commands (e.g. loops, compound commands, pipelines, etc.) all the way to a top level command, and consider it unsuccessful. On the other hand, non-fatal errors are usually swallowed by intermediate commands, and the execution is allowed to continue.

Ultimately it is up to the caller to decide how to handle fatal vs non-fatal errors.

Required Methods

fn is_fatal(&self) -> bool

Checks whether the error should be considered a "fatal" error.
